Keyless Access is a key-free locking and igni-
tion system to unlock and lock the vehicle
without actively using its key. To do this, all
that is required is to have a valid vehicle key in
the detection area where you are attempting
to access the vehicle

Opening and closing
The vehicle interior monitoring and the anti-
t o
w syst
em are automatically switched on
again next time the vehicle is locked.
The vehicle interior monitoring and anti-tow
sensor (tilt sensor) are automatically switch-
ed on when the anti-theft alarm is switched
on. In order to activate it, all the doors and
the rear lid must be closed.
If you wish to switch off the vehicle interior
monitoring and the anti-tow system, it must
be done each time that the vehicle is locked;
if not, they will be automatically switched on.
The vehicle interior monitoring and the anti-
tow system should be switched off if animals
are left inside the locked vehicle (otherwise,
their movements will trigger the alarm) or
when, for example, the vehicle is transported
or has to be towed with only one axle on the
ground.
False alarms
Interior monitoring will only operate correctly
if the vehicle is completely closed. Please ob-
serve related legal requirements.
The following cases may cause a false
alarm:

Air conditioning
Functioning mode of automatic air recircu-
l ation (air conditioning menu)
With the aut omatic air r
ecirculation mode ac-
tivated, the entry of fresh air into the cabin in-
terior is enabled. If the system detects a high
concentration of hazardous substances in the
ambient air, air recirculation mode is switched
on automatically. When the level of impurities
drops to within a normal range, recirculation
mode is switched off.
The system is unable to detect unpleasant
smells.
The air recirculation will not connect auto-
matically in versions without humidity sensor
and in the following external conditions:

Operating modes
Instructions for navigation When the Infotainment system is unable to re-
ceive any dat
a fr
om GPS satellites (due to a
dense tree canopy, underground car park),
navigation can still continue using the vehicle
sensors.
Possible limitations in navigation
In areas that are not or are only partially digi-
tised on the data storage device (e.g. insuffi-
cient definition of one-way streets and road
categories), the Infotainment system will still
attempt to provide route guidance.
Navigation area and updating navigation
data
Roads and streets are subject to constant
change (e.g. new roads, changes to street
names and building numbers). Therefore, if
the navigation data is not updated, then er-
rors or inaccuracies may occur during guid-
ance.
SEAT recommends updating navigation data
on a regular basis. Up to date navigation data
can be downloaded from www.seat.com or
acquired at a SEAT dealer. Updating and using navigation da-
ta fr
om an SD car

d  Only available for the model: Navi System
The Inf ot

ainment system always requires the
navigation data that is currently valid for this
unit in order to allow all functions to be used
in full. Using an old version may lead to errors
during navigation.
Updating navigation data
The current navigation data can be downloa-
ded in the internet at www.seat.com and stor-
ed in a SD card compatible with the unit.
Suitable SD Cards can be acquired at SEAT
dealerships.
The procedure is described on the internet at
www.seat.com.
